Re: [platform-ui-dev] How to rename a view ID on an namespace-restructur

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Hi Tom,

 

Your approach sounds very interesting !

 

But I’m concerned that the migration code registered through the e4 extension point would be _always_ executed regardless of whether it’s needed or not.

That would obviously degrade startup performance which feels like a no-go to me.

 

Or is there any possibility binding execution of such migration code to a condition like “old view ID is being processed” while an old workspace is being opened ?

 

Thanks,

Martin

You can ship a model processor through the e4 extension point and walk the model removing the references or even adjust the id pointing to the new view id

Hi Platform/UI experts,

 

As part of the TM Terminal restructuring that we’ve done recently, we’ve changed the ID of a view to the new namespace.

 

This causes issues when the view was active in a perspective when the update is applied:
After Eclipse restarts, the now-obsolete view shows up in an error state.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=466644

 

Do you see any way we could avoid this ? For instance, provide plugin.xml markup that would specify the view as “no longer existant thus close on restart”.

We thought about a PerspectiveListener, but we’d like to avoid unnecessary plugin activation if possible.

If you have any thought or idea, we’d really appreciate a comment on the bug !

 

Thanks,

Martin
